Multiplication Strategies Breaking large numbers into smaller numbers before multiplying

Multiplication Strategies When solving larger facts, it is often helpful to break it into smaller facts that are easier to remember. Then, just add the two facts to get your answer. Example: 11x12=(10x12)+(1x12) 11x12= x12=132

Multiplication Strategies  Another way to break it apart could involve breaking the 11 into 8+3.  Both strategies help the student get the correct answer. It just depends on which way makes more sense to the problem solver.

Multiplication Strategies This student started with 12x12. They probably chose 10x12 and 2x12 because those were facts they had memorized. 12x12=(10x12)+(2x12) 12x2= x2=144

Multiplication Strategies  Another strategy is called halving and doubling.  In halving and doubling, students half one number and double the product to find the answer to a larger fact.  Half of 12 is 6  6x12=72  72 doubled is 144
